Charge 3 stopped working

[Eulatide]

Hi, I got my charge 3 in May 2020. Around 2 weeks ago, after having no problems with it until then, my screen kept going blank and then coming up with either a single line or the smiley face. After rebooting several times to no avail, it started working again - for a day. The next morning the screen was completely blank, however it was still tracking everything when I synced to my app, again this only lasted for a day. It is now completely useless. Even when connected to the charger the screen is blank, and when I sync to the app it is saying that the charge 3 has no battery life, despite being in the charger for hours.

I would like to know how to go about replacing this product as it is still under warranty. Thank you.

Welcome to the Fitbit Community @Eulatide.

Thank you for the information provided and for trying to resolve the issue with your Fitbit Charge 3 before contacting us.

In addition to the regular restart, you can find some other troubleshooting steps to resolve battery issues here.

You can also try a long restart by doing the following:

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again.

Hope this helps.

Thanks for the reply, however, I have tried this and it is still not
working. No vibrations and no icons on the screen.
